IP means Internet Protocol. Every device in an IP-based Network including routers, print server, and host PCs, needs an IP address to identify its location on the network. To avoid address conflicts, IP addresses are publicly registered with the Network Information Centre (NIC). Having a unique IP address is mandatory for those devices participated in the public network but not in the private TCP/IP local area networks (LANs), such as host PCs under the management of a router since they do not need to be accessed by the public. Hence, the NIC has reserved certain addresses that will never be registered publicly. These are known as private IP addresses, and are listed in the following ranges:

As the router plays a role to manage and further protect its LAN, it interconnects groups of host PCs. Each of them has a private IP address assigned by the built-in DHCP server of the Vigor router. The router itself will also use the default private IP address: 192.168.1.1 to communicate with the local hosts. Meanwhile, Vigor router will communicate with other network devices through a public IP address. When the data flow passing through, the Network Address Translation (NAT) function of the router will dedicate to translate public/private addresses, and the packets will be delivered to the correct host PC in the local area network. Thus, all of the host PCs can share a common Internet connection.

To acquire a public IP address from your ISP for Vigor router as a customer premises equipment, there are three common protocols: Point to Point Protocol over Ethernet (PPPoE), PPPoA and MPoA. Multi-PVC is provided for more advanced setup of the above.

In ADSL deployment, the PPP (Point to Point)-style authentication and authorization is required for bridging customer premises equipment (CPE). Point to Point Protocol over Ethernet (PPPoE) connects a network of hosts via an access device to a remote access concentrator or aggregation concentrator. This implementation provides users with significant ease of use. Meanwhile it provides access control, billing, and type of service according to user requirement.

When a router begins to connect to your ISP, a serial of discovery process will occur to ask for a connection. Then a session will be created. Your user ID and password is authenticated via PAP or CHAP with RADIUS authentication system. And your IP address, DNS server, and other related information will usually be assigned by your ISP.

33..22 LLAANN

Local Area Network (LAN) is a group of subnets regulated and ruled by router. The design of network structure is related to what type of public IP addresses coming from your ISP.

33..22..11 BBaassiiccss ooff LLAANN

The most generic function of Vigor router is NAT. It creates a private subnet of your own. As mentioned previously, the router will talk to other public hosts on the Internet by using public IP address and talking to local hosts by using its private IP address. What NAT does is to translate the packets from public IP address to private IP address to forward the right packets to the right host and vice versa. Besides, Vigor router has a built-in DHCP server that assigns private IP address to each local host. See the following diagram for a briefly understanding.

In some special case, you may have a public IP subnet from your ISP such as

220.135.240.0/24. This means that you can set up a public subnet or call second subnet that each host is equipped with a public IP address. As a part of the public subnet, the Vigor router will serve for IP routing to help hosts in the public subnet to communicate with other public hosts or servers outside. Therefore, the router should be set as the gateway for public hosts.

DHCP Server Configuration

DHCP stands for Dynamic Host Configuration Protocol. The

router by factory default acts a DHCP server for your network so it

automatically dispatch related IP settings to any local user

configured as a DHCP client. It is highly recommended that you

leave the router enabled as a DHCP server if you do not have a

DHCP server for your network. If you want to use another DHCP server in the network other than

Vigor Router’s, you can let Relay Agent help you to redirect the

DHCP request to the specified location.

Enable Server - Let the router assign IP address to every host in the

LAN.

Disable Server – Let you manually assign IP address to every host

in the LAN.

Relay Agent – (1

subnet/2nd subnet) Specify which subnet that

DHCP server is located the relay agent should redirect the DHCP

request to.

Start IP Address - Enter a value of the IP address pool for the

DHCP server to start with when issuing IP addresses. If the 1st IP

address of your router is 192.168.1.1, the starting IP address must be

192.168.1.2 or greater, but smaller than 192.168.1.254.

IP Pool Counts - Enter the maximum number of PCs that you want

the DHCP server to assign IP addresses to. The default is 50 and the

maximum is 253.

Gateway IP Address - Enter a value of the gateway IP address for

the DHCP server. The value is usually as same as the 1st IP address

of the router, which means the router is the default gateway.

DHCP Server IP Address for Relay Agent - Set the IP address of

the DHCP server you are going to use so the Relay Agent can help to

forward the DHCP request to the DHCP server.

DNS Server Configuration

DNS stands for Domain Name System. Every Internet host must

have a unique IP address, also they may have a human-friendly,

easy to remember name such as www.yahoo.com. The DNS server

converts the user-friendly name into its equivalent IP address. Primary IP Address -You must specify a DNS server IP address

here because your ISP should provide you with usually more than

one DNS Server. If your ISP does not provide it, the router will

automatically apply default DNS Server IP address: 194.109.6.66 to

this field.

Secondary IP Address - You can specify secondary DNS server IP

address here because your ISP often provides you more than one

DNS Server. If your ISP does not provide it, the router will

automatically apply default secondary DNS Server IP address:

194.98.0.1 to this field.

The default DNS Server IP address can be found via Online Status:

Vigor2700 Series User’s Guide

If both the Primary IP and Secondary IP Address fields are left empty,

the router will assign its own IP address to local users as a DNS

proxy server and maintain a DNS cache.

If the IP address of a domain name is already in the DNS cache, the

router will resolve the domain name immediately. Otherwise, the

router forwards the DNS query packet to the external DNS server by

establishing a WAN (e.g. DSL/Cable) connection. There are two common scenarios of LAN settings that stated in Chapter 4. For the

configuration examples, please refer to that Chapter to get more information for your necessity.

33..33 NNAATT

Usually, the router serves as an NAT (Network Address Translation) router. NAT is a mechanism that one or more private IP addresses can be mapped into a single public one. Public IP address is usually assigned by your ISP, for which you may get charged. Private IP addresses are recognized only among internal hosts.

When the outgoing packets destined to some public server on the Internet reach the NAT router, the router will change its source address into the public IP address of the router, select the available public port, and then forward it. At the same time, the router shall list an entry in a table to memorize this address/port-mapping relationship. When the public server response, the incoming traffic, of course, is destined to the router’s public IP address and the router will do the inversion based on its table. Therefore, the internal host can communicate with external host smoothly.

The benefit of the NAT includes: z Save cost on applying public IP address and apply efficient usage of IP address.

NAT allows the internal IP addresses of local hosts to be translated into one public IP address, thus you can have only one IP address on behalf of the entire internal hosts.

z Enhance security of the internal network by obscuring the IP address. There are

many attacks aiming victims based on the IP address. Since the attacker cannot be aware of any private IP addresses, the NAT function can protect the internal network.

On NAT page, you will see the private IP address defined in RFC-1918. Usually we use the 192.168.1.0/24 subnet for the router. As stated before, the NAT facility can map one or more IP addresses and/or service ports into different specified services. In other words, the NAT function can be achieved by using port mapping methods.

33..33..11 PPoorrtt RReeddiirreeccttiioonn

Port Redirection is usually set up for server related service inside the local network (LAN), such as web servers, FTP servers, E-mail servers etc. Most of the case, you need a public IP address for each server and this public IP address/domain name are recognized by all users. Since the server is actually located inside the LAN, the network well protected by NAT of the router, and identified by its private IP address/port, the goal of Port Redirection function is to forward all access request with public IP address from external users to the mapping private IP address/port of the server.

Vigor2700 Series User’s Guide

The port redirection can only apply to incoming traffic. To use this function, please go to NAT page and choose Port Redirection web page. The

Port Redirection Table provides 10 port-mapping entries for the internal hosts.

Service Name Enter the description of the specific network service. Protocol Select the transport layer protocol (TCP or UDP). Public Port Specify which port can be redirected to the specified Private IP and

Port of the internal host. Private IP Specify the private IP address of the internal host providing the

service. Private Port Specify the private port number of the service offered by the internal

host. Active Check this box to activate the port-mapping entry you have defined. Note that the router has its own built-in services (servers) such as Telnet, HTTP and FTP etc.

Since the common port numbers of these services (servers) are all the same, you may need to reset the router’s in order to avoid confliction.

For example, the built-in web configurator in the router is with default port 80, which may conflict with the web server in the local network, http://192.168.1.13:80. Therefore, you need to change the router’s http port to any one other than the default port 80 to avoid conflict, such as 8080. This can be set in the System Maintenance >>Management. You then will access the admin screen of by suffixing the IP address with 8080, e.g., http://192.168.1.1:8080 instead of port 80.

As mentioned above, Port Redirection can redirect incoming TCP/UDP or other traffic on particular ports to the specific private IP address/port of host in the LAN. However, other IP protocols, for example Protocols 50 (ESP) and 51 (AH), do not travel on a fixed port. Vigor router provides a facility DMZ Host that maps ALL unsolicited data on any protocol to a single host in the LAN. Regular web surfing and other such Internet activities from other clients will continue to work without inappropriate interruption. DMZ Host allows a defined internal user to be totally exposed to the Internet, which usually helps some special applications such as Netmeeting or Internet Games etc.

While the broadband users demand more bandwidth for multimedia, interactive applications, or distance learning, security has been always the most concerned. The firewall of the Vigor router helps to protect your local network against attack from unauthorized outsiders. It also restricts users in the local network from accessing the Internet. Furthermore, it can filter out specific packets that trigger the router to build an unwanted outgoing connection.

The most basic security concept is to set user name and password while you install your router. The administrator login will prevent unauthorized access to the router configuration from your router.

If you did not set password during installation; you can go to System Maintenance to set up your password.

IIPP FFiilltteerrss

Depending on whether there is an existing Internet connection, or in other words “the WAN link status is up or down”, the IP filter architecture categorizes traffic into two: Call Filter and Data Filter.

z Call Filter - When there is no existing Internet connection, Call Filter is applied to all

traffic, all of which should be outgoing. It will check packets according to the filter rules. If legal, the packet will pass. Then the router shall “initiate a call” to build the Internet connection and send the packet to Internet.

z Data Filter - When there is an existing Internet connection, Data Filter is applied to

incoming and outgoing traffic. It will check packets according to the filter rules. If legal, the packet will pass the router.

The flooding-type attacks will attempt to exhaust all your system's resource while the vulnerability attacks will try to paralyze the system by offending the vulnerabilities of the protocol or operation system.

The DoS Defense function enables the Vigor router to inspect every incoming packet based on the attack signature database. Any malicious packet that might duplicate itself to paralyze the host in the secure LAN will be strictly blocked and a Syslog message will be sent as warning, if you set up Syslog server.

Also the Vigor router monitors the traffic. Any abnormal traffic flow violating the pre-defined parameter, such as the number of thresholds, is identified as an attack and the Vigor router will activate its defense mechanism to mitigate in a real-time manner.

The below shows the attack types that DoS/DDoS defense function can detect:

1. SYN flood attack

2. UDP flood attack

3. ICMP flood attack

4. TCP Flag scan

5. Trace route

6. IP options

7. Unknown protocol

8. Land attack

Vigor2700 Series User’s Guide

9. Smurf attack

10. SYN fragment

11. ICMP fragment

12. Tear drop attack

13. Fraggle attack

14. Ping of Death attack

15. TCP/UDP port scan

To provide an appropriate cyberspace to users, Vigor router equips with URL Content Filter not only to limit illegal traffic from/to the inappropriate web sites but also prohibit other web feature where malicious code may conceal.

Once a user type in or click on an URL with objectionable keywords, URL keyword blocking facility will decline the HTTP request to that web page thus can limit user’s access to the website. You may imagine URL Content Filter as a well-trained convenience-store clerk who won’t sell adult magazines to teenagers. At office, URL Content Filter can also provide a job-related only environment hence to increase the employee work efficiency. How can URL Content Filter work better than traditional firewall in the field of filtering? Because it checks the URL strings or some of HTTP data hiding in the payload of TCP packets while legacy firewall inspects packets based on the fields of TCP/IP headers only.

On the other hand, Vigor router can prevent user from accidentally downloading malicious codes from web pages. It’s very common that malicious codes conceal in the executable objects, such as ActiveX, Java Applet, compressed files, and other executable files. Once downloading these types of files from websites, you may risk bringing threat to your system. For example, an ActiveX control object is usually used for providing interactive web feature. If malicious code hides inside, it may occupy user’s system.

We all know that the content on the Internet just like other types of media may be inappropriate sometimes. As a responsible parent or employer, you should protect those in your trust against the hazards. With Web filtering service of the Vigor router, you can protect your business from common primary threats, such as productivity, legal liability, network and security threats. For parents, you can protect your children from viewing adult websites or chat rooms.

Once you have activated your Web Filtering service in Vigor router and chosen the categories of website you wish to restrict, each URL address requested (e.g.www.bbc.co.uk) will be checked against our server database, powered by SurfControl. The database covering over 70 languages and 200 countries, over 1 billion Web pages divided into 40 easy-to-understand categories. This database is updated as frequent as daily by a global team of Internet researchers. The server will look up the URL and return a category to your router. Your Vigor router will then decide whether to allow access to this site according to the categories you have selected. Please note that this action will not introduce any delay in your Web surfing because each of multiple load balanced database servers can handle millions of requests for categorization.

As a sub-functionality of IP Filter/Firewall, there are 15 types of detect/ defense function in the DoS Defense setup. The DoS Defense functionality is disabled for default.

Click Firewall and click DoS Defense to open the setup page.

Enable Dos Defense Check the box to activate the DoS Defense Functionality. Enable SYN flood

defense

Check the box to activate the SYN flood defense function. Once

detecting the Threshold of the TCP SYN packets from the Internet

has exceeded the defined value, the Vigor router will start to

randomly discard the subsequent TCP SYN packets for a period

defined in Timeout. The goal for this is prevent the TCP SYN

packets’ attempt to exhaust the limited-resource of Vigor router.

By default, the threshold and timeout values are set to 50 packets

per second and 10 seconds, respectively.

Enable UDP flood defense

Check the box to activate the UDP flood defense function. Once

detecting the Threshold of the UDP packets from the Internet has

exceeded the defined value, the Vigor router will start to randomly

discard the subsequent UDP packets for a period defined in

Timeout. The default setting for threshold and timeout are 150

packets per second and 10 seconds, respectively.

Enable ICMP flood defense

Check the box to activate the ICMP flood defense function. Similar

to the UDP flood defense function, once if the Threshold of ICMP

packets from Internet has exceeded the defined value, the router

will discard the ICMP echo requests coming from the Internet. The

default setting for threshold and timeout are 50 packets per second

and 10 seconds, respectively.

Enable PortScan detection

Port Scan attacks the Vigor router by sending lots of packets to

many ports in an attempt to find ignorant services would respond.

Check the box to activate the Port Scan detection. Whenever

detecting this malicious exploration behavior by monitoring the

Vigor2700 Series User’s Guide

port-scanning Threshold rate, the Vigor router will send out a

warning. By default, the Vigor router sets the threshold as 150

packets per second. Block IP options Check the box to activate the Block IP options function. The Vigor

router will ignore any IP packets with IP option field in the datagram

header. The reason for limitation is IP option appears to be a

vulnerability of the security for the LAN because it will carry

significant information, such as security, TCC (closed user group)

parameters, a series of Internet addresses, routing messages...etc. An

eavesdropper outside might learn the details of your private

networks.

Block Land

Check the box to enforce the Vigor router to defense the Land

attacks. The Land attack combines the SYN attack technology with

IP spoofing. A Land attack occurs when an attacker sends spoofed

SYN packets with the identical source and destination addresses, as

well as the port number to victims. Block Smurf Check the box to activate the Block Smurf function. The Vigor router

will ignore any broadcasting ICMP echo request. Block trace router Check the box to enforce the Vigor router not to forward any trace

route packets. Block SYN fragment Check the box to activate the Block SYN fragment function. The

Vigor router will drop any packets having SYN flag and more

fragment bit set. Block Fraggle Attack Check the box to activate the Block fraggle Attack function. Any

broadcast UDP packets received from the Internet is blocked.

Activating the DoS/DDoS defense functionality might block some

legal packets. For example, when you activate the fraggle attack

defense, all broadcast UDP packets coming from the Internet are

blocked. Therefore, the RIP packets from the Internet might be

dropped. Block TCP flag scan Check the box to activate the Block TCP flag scan function. Any TCP

packet with anomaly flag setting is dropped. Those scanning activities

include no flag scan, FIN without ACK scan, SYN FINscan, Xmas

scan and full Xmas scan.

Block Tear Drop Check the box to activate the Block Tear Drop function. Many

packets with a length greater than 1024 octets.

attack involves the perpetrator sending overlapping packets to the

target hosts so that those target hosts will hang once they

re-construct the packets. The Vigor routers will block any packets

realizing this attacking activity.

ICMP packets with more fragment bit set are dropped.

Check the box to enforce the Vigor router to defense the Land

attacks. The Land attack combines the SYN attack technology with

IP spoofing. A Land attack occurs when an attacker sends spoofed

SYN packets with the identical source and destination addresses, as

well as the port number to victims.

Block Unknown Protocol

Check the box to activate the Block Unknown Protocol function.

Individual IP packet has a protocol field in the datagram header to

indicate the protocol type running over the upper layer. However,

the protocol types greater than 100 are reserved and undefined at

this time. Therefore, the router should have ability to detect and

reject this kind of packets. Warning Messages We provide Syslog function for user to retrieve message from Vigor

router. The user, as a Syslog Server, shall receive the report sending

from Vigor router which is a Syslog Client. (Refer to System

Maintenance >> Syslog/Mail Alert for detail information.) All the warning messages related to DoS defense will be sent to user

and user can review it through Syslog daemon. Look for the keyword

DoS in the message, followed by a name to indicate what kind of

attacks is detected.

Based on the list of user defined keywords, the URL Content Filter facility in Vigor router inspects the URL string in every outgoing HTTP request. No matter the URL string is found full or partial matched with a keyword, the Vigor router will block the associated HTTP connection.

For example, if you add key words such as “sex”, Vigor router will limit web access to web sites or web pages such as “www.sex.com”, ”www.backdoor.net/images/sex/p_386.html”. Or you may simply specify the full or partial URL such as “www.sex.com” or “sex.com”.

each frame supports multiple keywords. The keyword could be a

noun, a partial noun, or a complete URL string. Multiple keywords

within a frame are separated by space, comma, or semicolon. In

addition, the maximal length of each frame is 32-character long.

After specifying keywords, the Vigor router will decline the

connection request to the website whose URL string matched to any

user-defined keyword. It should be noticed that the more simplified

the blocking keyword list, the more efficiently the Vigor router

perform.

Prevent web access from IP address

Check the box to deny any web surfing activity using IP address,

such as http://202.6.3.2. The reason for this is to prevent someone

dodges the URL Access Control. You must clear your browser cache first so that the URL content

filtering facility operates properly on a web page that you visited

The ISP often provides you with a dynamic IP address when you connect to the Internet via your ISP. It means that the public IP address assigned to your router changes each time you access the Internet. The Dynamic DNS feature lets you assign a domain name to a dynamic WAN IP address. It allows the router to update its online WAN IP address mappings on the specified Dynamic DNS server. Once the router is online, you will be able to use the registered domain name to access the router or internal virtual servers from the Internet. It is particularly helpful if you host a web server, FTP server, or other server behind the router.

Before you use the Dynamic DNS feature, you have to apply for free DDNS service to the DDNS service providers. The router provides up to three accounts from three different DDNS service providers. Basically, Vigor routers are compatible with the DDNS services supplied by most popular DDNS service providers such as www.dyndns.org, www.no-ip.com, www.dtdns.com, www.changeip.com, www.dynamic- nameserver.com. You should visit their websites to register your own domain name for the router.

Enable the Function and Add a Dynamic DNS Account

1. Assume you have a registered domain name from the DDNS provider, say

hostname.dyndns.org, and an account with username: test and password: test.

2. In the DDNS setup menu, check Enable Dynamic DNS Setup.

3. Select Index number 1 to add an account for the router. Check Enable Dynamic DNS

Account, and choose correct Service Provider: dyndns.org, type the registered hostname: hostname and domain name suffix: dyndns.org in the Domain Name block. The following two blocks should be typed your account Login Name: test and Password: test.

The Vigor router has a built-in real time clock which can update itself manually or automatically by means of Network Time Protocols (NTP). As a result, you can not only schedule the router to dialup to the Internet at a specified time, but also restrict Internet access to certain hours so that users can connect to the Internet only during certain hours, say, business hours. The schedule is also applicable to other functions.

You have to set your time before set schedule. In System Maintenance>> Time Setup menu, press Inquire Time button to set the Vigor router’s clock to current time of your PC. The clock will reset once if you power down or reset the router. There is another way to set up time. You can inquiry an NTP server (a time server) on the Internet to synchronize the router’s clock. This method can only be applied when the WAN connection has been built up.

You can set up to 15 schedules. Then you can apply them to your Internet Access. To add a schedule, please click any index, say Index No. 1. The detailed settings of the call

Remote Authentication Dial-In User Service (RADIUS) is a security authentication client/server protocol that supports authentication, authorization and accounting, which is widely used by Internet service providers. It is the most common method of authenticating and authorizing dial-up and tunneled network users.

The UPnP (Universal Plug and Play) protocol is supported to bring to network connected devices the ease of installation and configuration which is already available for directly connected PC peripherals with the existing Windows 'Plug and Play' system. For NAT routers, the major feature of UPnP on the router is “NAT Traversal”. This enables applications inside the firewall to automatically open the ports that they need to pass through a router. It is more reliable than requiring a router to work out by itself which ports need to be opened. Further, the user does not have to manually set up port mappings or a DMZ. UPnP is available on Windows XP and the router provides the associated support for MSN Messenger to allow full use of the voice, video and messaging features.

default value is 1812 , based on RFC 2138.

Enable UPNP Service Accordingly, you can enable either the Connection Control

Service or Connection Status Service.

After setting Enable UPNP Service setting, an icon of IP Broadband Connection on Router on Windows XP/Network Connections will appear. The connection status and control status will be able to be activated. The NAT Traversal of UPnP enables the multimedia features of your applications to operate. This has to manually set up port mappings or use other similar methods. The screenshots below show examples of this facility.

The UPnP facility on the router enables UPnP aware applications such as MSN Messenger to discover what are behind a NAT router. The application will also learn the external IP address and configure port mappings on the router. Subsequently, such a facility forwards packets from the external ports of the router to the internal ports used by the application.

Vigor2700 Series User’s Guide

The reminder as regards concern about Firewall and UPnP:

Can't work with Firewall Software

Enabling firewall applications on your PC may cause the UPnP function not working properly. This is because these applications will block the accessing ability of some network ports.

Security Considerations

Activating the UPnP function on your network may incur some security threats. You should consider carefully these risks before activating the UPnP function.

¾ Some Microsoft operating systems have found out the UPnP weaknesses and

hence you need to ensure that you have applied the latest service packs and patches.

¾ Non-privileged users can control some router functions, including removing

and adding port mappings.

The UPnP function dynamically adds port mappings on behalf of some UPnP-aware applications. When the applications terminate abnormally, these mappings may not be removed.

Deploying QoS (Quality of Service) management to guarantee that all applications receive the service levels required and sufficient bandwidth to meet performance expectations is indeed one important aspect of modern enterprise network.

One reason for QoS is that numerous TCP-based applications tend to continually increase their transmission rate and consume all available bandwidth, which is called TCP slow start. If other applications are not protected by QoS, it will detract much from their performance in the overcrowded network. This is especially essential to those are low tolerant of loss, delay or jitter (delay variation), such as voice over IP, videoconferencing, streaming video or data.

Another reason is due to congestions at network intersections where speeds of interconnected circuits mismatch or traffic aggregates, packets will queue up and traffic can be throttled back to a lower speed. If there’s no defined priority to specify which packets should be discarded (or in another term “dropped”) from an overflowing queue, packets of sensitive applications mentioned above might be the ones to drop off. How this will affect application performance?

Vigor2700 Series User’s Guide

There are two components within Primary configuration of QoS deployment: z Classification: Identifying low-latency or crucial applications and marking them for

high-priority service level enforcement throughout the network.

z Scheduling: Based on classification of service level to assign packets to queues and

associated service types

The basic QoS implementation in Vigor routers is to classify and schedule packets based on the service type information in the IP header. For instance, to ensure the connection with the headquarter, a teleworker may enforce an index of QoS Control to reserve bandwidth for HTTPS connection while using lots of application at the same time.

One more larger-scale implementation of QoS network is to apply DSCP (Differentiated Service Code Point) and IP Precedence disciplines at Layer 3. Compared with legacy IP Precedence that uses Type of Service (ToS) field in the IP header to define 8 service classes, DSCP is a successor creating 64 classes possible with backward IP Precedence compatibility. In a QoS-enabled network, or Differentiated Service (DiffServ or DS) framework, a DS domain owner should sign a Service License Agreement (SLA) with other DS domain owners to define the service level provided toward traffic from different domains. Then each DS node in these domains will perform the priority treatment. This is called per-hop-behavior (PHB). The definition of PHB includes Expedited Forwarding (EF), Assured Forwarding (AF), and Best Effort (BE). AF defines the four classes of delivery (or forwarding) classes and three levels of drop precedence in each class.

Vigor routers as edge routers of DS domain shall check the marked DSCP value in the IP header of bypassing traffic, thus to allocate certain amount of resource execute appropriate policing, classification or scheduling. The core routers in the backbone will do the same checking before executing treatments in order to ensure service-level consistency throughout the whole QoS-enabled network.

However, each node may take different attitude toward packets with high priority marking since it may bind with the business deal of SLA among different DS domain owners. It’s not easy to achieve deterministic and consistent high-priority QoS traffic throughout the whole network with merely Vigor router’s effort.

For more effective QoS deployment, you should check the available ADSL upstream and downstream speed in Online Status as indicated below before you configure the QoS setting.

A Virtual Private Network (VPN) is the extension of a private network that encompasses links across shared or public networks like the Internet. In short, by VPN technology, you can send data between two computers across a shared or public network in a manner that emulates the properties of a point-to-point private link.

users with the PAP protocol. Selecting this option means the router will attempt to

authenticate dial-in users with the CHAP protocol first. If the dial-in user does not support this protocol, it will fall back to use the PAP protocol for authentication.

This option represents that the MPPE encryption method will be optionally employed in the router for the remote dial-in user. If the remote dial-in user does not support the MPPE encryption algorithm, the router will transmit “no MPPE encrypted packets”. Otherwise, the MPPE encryption scheme will be used to encrypt the data.

Require MPPE (40/128bits) - Selecting this option will force the router to encrypt packets by using the MPPE encryption algorithm. In addition, the remote dial-in user will use 128-bit to perform encryption prior to using 40-bit for encryption. In other words, if 128-bit MPPE encryption method is not available, then 40-bit encryption scheme will be applied to encrypt the data. Maximum MPPE - This option indicates that the router will only use the MPPE encryption scheme with maximum bits (128 bits) to encrypt the data.

In IPSec General Setup, there are two major parts of configuration. There are two phases of IPSec. ¾ Phase 1: negotiation of IKE parameters including encryption, hash, Diffie-Hellman

parameter values, and lifetime to protect the following IKE exchange, authentication of both peers using either a Pre-Shared Key or Digital Signature (x.509). The peer that starts the negotiation proposes all its policies to the remote peer and then remote peer tries to find a highest-priority match with its policies. Eventually to set up a secure tunnel for IKE Phase 2.

The Mutual Authentication function is mainly used to communicate with other routers or clients who need bi-directional authentication in order to provide stronger security, for example, Cisco routers. So you should enable this function when your peer router requires mutual authentication. You should further specify the User Name and Password of the mutual authentication peer.

should choose an IP address from the local private network. For example, if the local private network is

192.168.1.0/255.255.255.0, you could choose 192.168.1.200 as the Start IP Address. But, you have to notice that the first two IP addresses of 192.168.1.200 and 192.168.1.201 are reserved for ISDN remote dial-in user.

Vigor2700 Series User’s Guide

¾ Phase 2: negotiation IPSec security methods including Authentication Header (AH) or

Encapsulating Security Payload (ESP) for the following IKE exchange and mutual examination of the secure tunnel establishment.

There are two encapsulation methods used in IPSec, Transport and Tunnel. The Transport mode will add the AH/ESP payload and use original IP header to encapsulate the data payload only. It can just apply to local packet, e.g., L2TP over IPSec. The Tunnel mode will not only add the AH/ESP payload but also use a new IP header (Tunneled IP header) to encapsulate the whole original IP packet.

Authentication Header (AH) provides data authentication and integrity for IP packets passed between VPN peers. This is achieved by a keyed one-way hash function to the packet to create a message digest. This digest will be put in the AH and transmitted along with packets. On the receiving side, the peer will perform the same one-way hash on the packet and compare the value with the one in the AH it receives.

Encapsulating Security Payload (ESP) is a security protocol that provides data confidentiality and protection with optional authentication and replay detection service.

IKE Authentication Method This usually applies to those are remote dial-in user or node

(LAN-to-LAN) which uses dynamic IP address and IPSec-related VPN connections such as L2TP over IPSec and IPSec tunnel.

Pre-Shared Key- Specify a key for IKE authentication Re-type Pre-Shared Key-Confirm the pre-shared key.

IPSec Security Method Medium - Authentication Header (AH) means data will be

authenticated, but not be encrypted. By default, this option is active. High - Encapsulating Security Payload (ESP) means payload (data) will be encrypted and authenticated. You may select encryption algorithm from Data Encryption Standard (DES), Triple DES (3DES), and AES.

A digital certificate works as an electronic ID, which is issued by a certification authority (CA). It contains information such as your name, a serial number, expiration dates etc., and the digital signature of the certificate-issuing authority so that a recipient can verify that the certificate is real. Here Vigor router support digital certificates conforming to standard X.509.

Any entity wants to utilize digital certificates should first request a certificate issued by a CA server. It should also retrieve certificates of other trusted CA servers so it can authenticate the peer with certificates issued by those trusted CA servers.

The standard format of SIP URI is

Some fields may be optional in different use. In general, "host” refers to a domain. The “userinfo” includes the user field, the password field and the @ sign following them. This is very similar to a URL so some may call it “SIP URL”. SIP supports peer-to-peer direct calling and also calling via a SIP proxy server (a role similar to the gatekeeper in H.323 networks), while the MGCP protocol uses client-server architecture, the calling scenario being very similar to the current PSTN network.

After a call is setup, the voice streams transmit via RTP (Real-Time Transport Protocol). Different codecs (methods to compress and encode the voice) can be embedded into RTP packets. Vigor V models provide various codecs, including G.711 A/µ-law, G.723, G.726 and G.729 A & B. Each codec uses a different bandwidth and hence provides different levels of voice quality. The more bandwidth a codec uses the better the voice quality, however the codec used must be appropriate for your Internet bandwidth.

Usually there will be two types of calling scenario, as illustrated below:

z Calling via SIP Servers

First, the Vigor V models of yours will have to register to a SIP Registrar by sending registration messages to validate. Then, both parties’ SIP proxies will forward the sequence of messages to caller to establish the session.

If you both register to the same SIP Registrar, then it will be illustrated as below:

Vigor2700 Series User’s Guide

The major benefit of this mode is that you don’t have to memorize your friend’s IP address, which might change very frequently if it’s dynamic. Instead of that, you will only have to using dial plan or directly dial your friend’s account name if you are with the same SIP Registrar. Please refer to the Example 1 and 2 in the Calling Scenario.

z Peer-to-Peer

Before calling, you have to know your friend’s IP Address. The Vigor VoIP Routers will build connection between each other. Please refer to the Example 3 in the Calling

Scenario.

Our Vigor V models firstly apply efficient codecs designed to make the best use of available bandwidth, but Vigor V models also equip with automatic QoS assurance. QoS Assurance assists to assign high priority to voice traffic via Internet. You will always have the required inbound and outbound bandwidth that is prioritized exclusively for Voice traffic over Internet but you just get your data a little slower and it is tolerable for data traffic.
